* hw/arm/armsse: Allow boards to specify init-svtorPeter Maydell2019-02-211-0/+3
| | | | | | | | | | | | The Musca boards have DAPLink firmware that sets the initial secure VTOR value (the location of the vector table) differently depending on the boot mode (from flash, from RAM, etc). Export the init-svtor as a QOM property of the ARMSSE object so that the board can change it.

* hw/char/pl011: Support all interrupt linesPeter Maydell2019-02-211-1/+1
| | | | | | | | | | | | | | | | | The PL011 UART has six interrupt lines: * RX (receive data) * TX (transmit data) * RT (receive timeout) * MS (modem status) * E (errors) * combined (logical OR of all the above) So far we have only emulated the combined interrupt line; add support for the others, so that boards that wire them up to different interrupt controller inputs can do so.

* hw/misc/tz-ppc: Support having unused ports in the middle of the rangePeter Maydell2019-02-211-1/+7
| | | | | | | | | | | | | | | | | | | | The Peripheral Protection Controller's handling of unused ports is that if there is nothing connected to the port's downstream then it does not create the sysbus MMIO region for the upstream end of the port. This results in odd behaviour when there is an unused port in the middle of the range: since sysbus MMIO regions are implicitly consecutively allocated, any used ports above the unused ones end up with sysbus MMIO region numbers that don't match the port number. Avoid this numbering mismatch by creating dummy MMIO regions for the unused ports. This doesn't change anything for our existing boards, which don't have any gaps in the middle of the port ranges they use; but it will be needed for the Musca board.

| * spapr/irq: add an 'nr_irq' parameter to initialize the backend.Cédric Le Goater2019-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using the 'dual' interrupt mode, the source numbers of both sPAPR IRQ backends are aligned to share a common IRQ number space and to use a similar mapping of the machine qemu_irq array which is indexed by the source number. The XICS IRQ number range initially being [ 0x1000 - 0x2000 ], this requires to change the XICS ICSState offset to 0 and to provision for an extra 4K of source numbers and qemu_irqs which will never be used by the machine when running under the XICS interrupt mode. This is not an optimal solution. Change the init() method to allocate an IRQ number space of the expected size for the XICS sPAPR IRQ backend. It breaks the interrupt signaling when under the 'dual' mode because source numbers have unexpected values but next patch will fix that.

| * qdev: pass an Object * to qbus_set_hotplug_handler()Michael Roth2019-02-171-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain devices types, like memory/CPU, are now being handled using a hotplug interface provided by a top-level MachineClass. Hotpluggable host bridges are another such device where it makes sense to use a machine-level hotplug handler. However, unlike those devices, host-bridges have a parent bus (the main system bus), and devices with a parent bus use a different mechanism for registering their hotplug handlers: qbus_set_hotplug_handler(). This interface currently expects a handler to be a subclass of DeviceClass, but this is not the case for MachineClass, which derives directly from ObjectClass. Internally, the interface only requires an ObjectClass, so expose that in qbus_set_hotplug_handler(). Cc: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | | Add the ability for a caller to wait for completion of the background thread to synchronously dispatch its result, without needing to wait for the main loop to run the idle callback. This method needs very careful usage to avoid a dangerous race condition with the free'ing of the task. The completion callback is normally invoked from an idle callback registered with the main loop context. The qio_task_wait_thread method must only be called if the completion callback has not yet run. The only safe way to achieve this is to run the qio_task_wait_thread method from the thread that executes the main loop. It is generally a bad idea to use this method since it will block execution of the main loop, however, the design of the character devices and its usage from vhostuser already requires blocking execution.

* chardev: fix mess in OPENED/CLOSED events when muxedArtem Pisarenko2019-02-121-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | When chardev is multiplexed (mux=on) there are a lot of cases where CHR_EVENT_OPENED/CHR_EVENT_CLOSED events pairing (expected from frontend side) is broken. There are either generation of multiple repeated or extra CHR_EVENT_OPENED events, or CHR_EVENT_CLOSED just isn't generated at all. This is mostly because 'qemu_chr_fe_set_handlers()' function makes its own (and often wrong) implicit decision on updated frontend state and invokes 'fd_event' callback with 'CHR_EVENT_OPENED'. And even worse, it doesn't do symmetric action in opposite direction, as someone may expect (i.e. it doesn't invoke previously set 'fd_event' with 'CHR_EVENT_CLOSED'). Muxed chardev uses trick by calling this function again to replace callback handlers with its own ones, but it doesn't account for such side effect. Fix that using extended version of this function with added argument for disabling side effect and keep original function for compatibility with lots of frontends already using this interface and being "tolerant" to its side effects. One more source of event duplication is just line of code in char-mux.c, which does far more than comment above says (obvious fix).

Unfortunately we forgot to check whether other parts of the code were doing comparisons against tb->cflags that would need to be updated. It turns out that there is exactly one such place: the tb_lookup__cpu_state() function checks whether the TB it has found in the tb_jmp_cache has a tb->cflags matching the cf_mask that is passed in. The tb->cflags has the cluster_index in it but the cf_mask does not. Hoist the "add cluster index to the cf_mask" code up from tb_htable_lookup() to tb_lookup__cpu_state() so it can be considered in the "did this TB match in the jmp cache" condition, as well as when we do the full hash lookup by physical PC, flags, etc. (tb_htable_lookup() is only called from tb_lookup__cpu_state(), so this change doesn't require any further knock-on changes.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These changes (along with corresponding Linux kernel and qboot changes) enable a guest to be booted using the x86/HVM direct boot ABI. This commit adds a load_elfboot() routine to pass the size and location of the kernel entry point to qboot (which will fill in the start_info struct information needed to to boot the guest). Having loaded the ELF binary, load_linux() will run qboot which continues the boot. The address for the kernel entry point is read from an ELF Note in the uncompressed kernel binary by a helper routine passed to load_elf().
